still years away from perfecting a nuclear weapon, but they are getting closer all the time. the threat of a preemptive strike on the united states, even if that's in the possible now, is terrifying. >> you have to take this seriously. >> reporter: north korea does not yet have a missile capable of hitting the continental u.s. but america has satellites in space, radars at sea and on the ground, designed to detect a missile launch. then dozens of intercepting missiles could be fired from california or alaska to take out enemy missiles, even nuclear ones, before they reach america. but the system is far from foolproof. however, the most immediate threat tonight from north korea is far more conventional. they could fire on south korea, america's ally, like they've done before. >> this is how wars start. threats become maneuvers, become exchanges, are met are retaliation. pretty soon, you have world war i or vietnam. >> reporter: and there is renewed concern tonight about

mobile missile launchers in north korea, which could fire rockets capable of hitting south korea. there is nothing imminent, but these threatening statements have everyone on edge. diane? >> all right, martha raddatz, thank you so much. and now we turn to another surprising headline tonight. a secret operation has succeeded in capturing another bin laden. this time, the son-in-law. he has been brought to the united states. so, how did they find him? and what is he saying tonight? abc's chief investigative correspondent brian ross has been reporting the story all day. >> reporter: in the world of al qaeda, he was the guy who married the boss' daughter, which gave him a place of prominence next to osama bin laden. but sulaiman abu ghaith never took over the family terror business and became better known as the loudmouth son-in-law. the al qaeda spokesman who proclaimed his delight in this video over the 9/11 attacks on the united states.

there wasn't even a reward posted for the son-in-law on the u.s. rewards for justice terrorism website. but the cia has been tracking abu ghaith for years, according to u.s. officials, as he moved first from afghanistan to iran and then, in january, into turkey, where he was arrested based on a u.s. tip. >> once he left iranian territory and got into turkey, with very close monitoring by u.s. government agencies, he was -- his days were numbered. >> reporter: the turks then sent abu ghaith to jordan, where, before being sent onto new york, officials tell abc news, the significance of his capture became apparent, as he revealed new details on the current status, personnel and finances of al qaeda. >> this is a man who was in the inner circle of bin laden's al qaeda operations and now we have him alive and he's talking. >> reporter: growing up, bin laden has made the family targets wherever they go. in the 2011 u.s. raid on bin laden's hideout in pakistan, at least one son was killed.

a second son had been killed in an earlier drone strike. abu ghaith is already in the u.s. and will appear before a federal imagine strait here in new yo new york tomorrow morning. an indication he'll be put on public trial, not before military judges in guantanamo. facing charges of conspiracy to kill u.s. citizens. diane? >> all right, brian, thanks so much. and now, we give you a note on what is happening in rome. there he was, cardinal man, from vietnam, arriving at the vatican. and he is the last of the 115 voting cardinals to arrive in the city for the election of a new pope. the cardinals say this makes it possible now to announce the dates of the voting conclave soon. and we turn next to the winter storm which hit areas of this country already ravaged by hurricane sandy four months ago. and abc's ron claiborne was there as the wind and the rain moved in again. >> reporter: tonight, the late winter storm is delivering one last blow, to coastal new england. waves lapping at the doorsteps

cia director, but only after senator paul got his answer. no. the president cannot kill an unarmed u.s. citizen here at home with a drone. senator paul told us it was a clear-cut victory. but not one likely to be repeated. see yourself doing this again? >> not any time soon. >> reporter: jonathan karl, abc news, washington. and we turn next to a story affecting every american family. here's the question. are your earphones ruining your hearing? right now, tonight? are millions and millions of americans walking around, listening to music, but ensuring they will not be able to hear as well in the years ahead? tonight, the mayor of new york says it's time to send out an alarm. and abc's chief medical editor dr. richard besser is stepping in. >> reporter: 30 years ago, people in their 20s could all hear the rustle of leaves. the drip of a raindrop. the babble of children.
